- following is'a specification;

' The present invention 'relates to a device foi'ispraymg liquids, and has particular ich crence to that class yof such. devices which;v are employed to spray liquid fuel into thc,

' ir chamber of a carbureter. y

An important objectof tlie'inventioii 'is' toprovide means of the above'mentioned character, which will spraythe liquid fuel in a Iine sniokelike spray orvapor inv `two streams ruiming in opposite directions,; in the presence of air, whereby the fuel is iiitimately mixed with the air "forming acari-` b ur'eted gas of high eiiciency.

provide means' of "the above `vmentioned character, having adjustable parts so that the inenes's of the spray of the liquid fuel may be regulated. A

A further objectoof this invention is' to provide a' device of the above mentioned character, which is simple in construction,

easy to o erate, and. cheap manufact-ure. A' fui-t ier object of this invention is to 'provide n device ofA the above mentioned fcharacter, 'which will provide a substantially spherical spray ofthe liquid fuel,

thus exposingthe max iniuniarea ofsuch In theaccoinpanyin'g drawings forming a part. of this specification and infwhicli' like numerals are employed to designate like parts throughout the same, Figure' 1 is a side view of a carburetor, portions thereof being broken away to show my iin'- proved spraying device arranged therein,
